Blue Tsunami Dries Up In 1 State

While Democrats celebrated major victories across the country in the 2026 midterm elections, voters in South Dakota delivered a very different result, handing Republicans decisive wins in several important statewide races.

The Republican Party successfully defended the governor’s office, retained a U.S. Senate seat, and maintained control of the state’s only seat in the U.S. House of Representatives.

The results demonstrated that despite the Democratic momentum seen elsewhere, South Dakota remains firmly in Republican hands.

Republican Sen. Mike Rounds secured another six-year term in Washington, defeating independent challenger Brian Bengs by a substantial margin.

Rounds received approximately 60.5% of the vote, compared with 39.5% for Bengs, according to unofficial election results.

The victory gives Rounds a third term in the Senate and ensures that South Dakota will continue to have an experienced Republican representing the state in Congress.

Rounds’ reelection came as Republicans faced a much more difficult political environment nationally, with Democrats making significant gains in several states.

South Dakota Republicans Hold Governor’s Office

The Republican success extended to the governor’s race, where incumbent Gov. Larry Rhoden defeated Democratic challenger Dan Ahlers.

Rhoden captured approximately 63.5% of the vote, while Ahlers received about 36.5%.

The decisive victory gives Rhoden his first elected term as governor after he assumed the office in 2025 when former Gov. Kristi Noem departed to serve in President Donald Trump’s administration.

Rhoden had previously served as lieutenant governor and entered the election with years of experience in South Dakota politics.

His victory allows Republicans to continue directing state policy in areas such as taxes, government spending, agriculture, education, and economic development.

South Dakota has long been considered one of the nation’s most dependable Republican states, and the governor’s race reinforced that political tradition.

Republicans Secure Another Congressional Victory

Republicans also celebrated a significant victory in South Dakota’s race for the U.S. House of Representatives.

Republican Marty Jackley, the state’s longtime attorney general, defeated Democrat Nicole “Nikki” Gronli to win South Dakota’s single congressional seat.

Jackley received approximately 64% of the vote, compared with 36% for Gronli.

His victory ensures that the state’s entire congressional delegation will remain Republican.

Jackley brings extensive experience in law enforcement and state government to his new position in Washington.

His election also gives Republicans another voice in Congress as lawmakers prepare for debates over federal spending, border security, taxes, and the direction of national policy.

Democratic Gains Fail To Break Republican Control

The statewide results were especially noteworthy because of the broader political environment surrounding the 2026 midterm elections.

Democrats made substantial gains nationally, creating new challenges for Republicans and reshaping the balance of power in Washington.

However, that momentum did not translate into victories in South Dakota’s major statewide contests.

Republican candidates won the races for governor, U.S. Senate, and U.S. House by comfortable margins.

The GOP also captured several other statewide offices, including secretary of state, attorney general, state auditor, and state treasurer.

Democrats did make some progress in the state Legislature, gaining seats in the South Dakota House. Nevertheless, Republicans maintained overwhelming majorities in both legislative chambers.

The outcome illustrates an important distinction between national political trends and individual state elections.

Although voters in some parts of the country supported Democratic candidates, South Dakota voters continued to favor Republican leadership at the state and federal levels.

What The Results Mean For Republicans

South Dakota’s election results offer Republicans a clear example of the party’s continued strength in traditionally conservative states.

The victories of Rounds, Rhoden, and Jackley demonstrate that Republican candidates can still win by substantial margins even during an election cycle marked by Democratic success elsewhere.

The outcome also places South Dakota in a position to remain an important Republican stronghold as both parties begin preparing for the next presidential election.

For Democrats, the results highlight the difficulty of expanding their electoral coalition into states where Republicans have maintained a strong advantage for decades.

While the national political landscape may have shifted following the midterms, South Dakota’s voters delivered a consistent message through their ballots.

Republicans will continue controlling the governor’s office, holding both U.S. Senate seats, and representing the state’s lone congressional district.

The Democratic wave may have changed the political balance in Washington, but in South Dakota, Republican control remains firmly intact.
